Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a simple, efficient method for treating photoresist development waste liquid containing a photoresist and tetraalkyl ammonium ion by introducing a process in which the liquid is contacted with an anion exchanger. SOLUTION: Photoresist development waste liquid containing a photoresist and tetraalkyl ammonium ion, or the concentrated liquid mainly containing tetraalkyl ammonium ion (for example, the concentrated liquid by electrodialysis or electrolysis), or the neutralized liquid (obtained by neutralizing the development waste liquid and removing the insolubilized photoresist by filtration etc.) is contacted with an anion exchanger so that the photoresist is absorbed by the anion exchanger to be removed.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To generate large power despite a narrow, occupied area, taking advantage of buoyancy of a float, by linking many floats together to accommodate them in an erected part, sending falling-water-floats one by one into the erected part, and driving a generator by means of a turbine driven by the hydraulic power obtained through the buoyancy of the float. SOLUTION: A plurality of floats 6 in which inert gas such as hydrogen or herium is enclosed are connected endlessly by using universal joints 13, and each float 6 is moved (elevated) from a lower U-shaped turning part 1d into a primary erected pipe part 1a. At this time, no water leaks, and each float 6 is sent to a secondary erected pipe part 1b via an upper U-shaped turning pipe part 1c. Then, air is sent with pressure into the primary erected pipe part 1a by means of a compressor 15, so that ascending pressure is applied to the fluid within the pipe, thereby rapidly elevating the float 6. Thus, large pressure is applied to the water, and pressurized water is sent from an inclined, connecting pipe 3 into a falling-water flow pipe part 2, so that a turbine 7 is driven by the water flow at this time in order to activate an generator 9.

Title: Subscriber circuit
Inventor: ARAI MASANOBU
IPC: H04Q3/42
Filed: 1986-11-10
Abstract: PURPOSE:To simplify the titled circuit by adding a signal through two-wire subscriber line and a signal through four-wire input line, then passing a subscriber circuit through an input impedance synthesizing filter. CONSTITUTION:The digital filter 14 outputs an output signal so as to obtain a desired two-wire-side input impedance and a desired transfer characteristic HZ for transfer from the four-wire input line to the two-wire subscriber line. An adder 15 adds the output VD of this digital filter 14 with the voltage VL of the two-wire subscriber line. A resistor 12 of a resistance value R, a voltage buffer amplifier 13, and the adder 15 constitute a driver circuit 18 to drive the two-wire subscriber line 1, and acts as a current source that outputs a current: I=-VD/R. The characteristic of the transfer from the four-wire input line to the two-wire subscriber line can obtain a desired input impedance characteristic Zin and a transmitting characteristic HZ by selecting the value of HZ=R /Zin assuming that a load ZL is connected to a terminal 1. As a result, frequency characteristic correction filter can be omitted, hence the titled circuit can be simplified.
